Or you can keep it real simple. Use one extension cord for these 2 devices. In a home shop that's hardly a nuisance. I do it frequently as I only have one 30 amp 240v circuit available in my garage, but 3 welders that can be used. Obviously I'm not going to use 2 welders at once.

Eventually that will be remedied with a new sub panel but I'm still only going to have one 50A plug for the trio of welders. Everything else is on 120v so I will have 3-4 new circuits for the appropriate requirements.
